Specification of Letters Patent.

Patented June 16, 1908.

Application filed September 5, 1907. Serial No. 391,457.

T 0 all whom it may concern:

Be it known that 1, CHARLES A. BURNS, a citizen of the United States,and a resident of the city of New York, borough of Manhattan, in thecounty and State of New York, have invented new and useful Improvementsin Stools, of which the following is a full, clear, and exactdescription.

This invention has reference to improvements in stools more especiallydesigned as a piano stool, and has for an object primarily to providefor the convenient adjustment of the stool seat to the desired elevationwithout rendering said seat shaky or insecure. This object I accomplishby providing each leg of the stool with a succession of blocks hingedthereto and hinged to each other, each block having projecting portionsat opposite ends fitting into counterpart portions of adjacent blocks,and a seat adapted to rest directly on the legs or rest on thecorresponding blocks of the legs.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a perspective view of a stool complete, embodying myinvention. Fig. 2 is a fragmentary sectional view substantially on theline 2-2 of Fig. 1; Fig. 3 is a side view of the upper end of one of thestool legs;

and Fig. 4 is a cross-section of one of the legs, illustrating themanner in which it is braced.

The stool shown on the accompanying drawing includes four legs 5 whichare diagonally arranged at the corners of the stool and are rigidlyconnected at an intermediate point of their length by cross-bars 6, thelat ter being reinforced by diagonally disposed braces 7 which, as bestshown in Fig. 4;, are in close contact with the inner faces of the legsand are mortised into the bars 6.

The top of each of the legs 5 is rabbeted at its inner edge to form ashoulder 8 on which a seat 9 for the stool is adapted to bear when saidseat is at its minimum height.

Adjacent to the shoulder 8 on the inner face of each leg is hingedlyconnected one or more stepped or Z-shaped blocks 10, the said blocksbeing also likewise hinged together, each being a counterpart of therabbeted portion of the leg and of each other, whereby they may besuccessfully turned into alinement with the legs and form an extendedportion thereof, thus adapting the seat to be supported at substantiallyany desired elevation. The blocks when turned into alinement neatly fitone within the other, by which I mean that the projecting portions atthe opposite ends of each block fill in the removed or rabbeted portionsof the adjacent blocks.

As shown, the corners of the seat 9 are notched for receiving the outerextended portions of the legs 5 or blocks 10, which prevents lateraldisplacement of the seat when in operative position. The seat is furtherheld against displacement when resting on the legs or blocks byprojections or pins 11, the said pins being arranged on the under faceof the seat adjacent to the corners, and are received in correspondingrecesses 12 formed in the rabbeted or depressed portion of each blockand in each leg.

While I'have shown my improvement applied to a stool, moreparticularlyconstructed. as a iano stool, it is obvious that the samemay e applied to chairs; etc., and the number of legs increased ordiminished as desired; also various other changes may be made in thedetailed construction of the stool within the scope of the invention asdefined in the claims annexed.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. A stool comprising a plurality of legs rabbeted at their upper endsadjacent to the inner edges, providing shoulders, a seat adapted to beseated on said shoulders having notches for receiving the extendedportions of the legs, and a succession of stepped blocks hinged to eachlegend to each other for extending the length of the legs and varyingthe elevation of the seat.

2. A stool comprising a plurality of legs, each of which is rabbeted atits upper end adj acent to the inner edge, providing a shoulder, a seatadapted to be seated on the shoulders of the legs having notches forreceiving the extended portions thereof, and projections on the underface of the seatadapted to engage corresponding recesses formed in theshoulders for the purpose described.

3. An article of furniture comprising legs adapted to support a seat andhaving their upper ends rabbeted, and a plurality of substantiallyZ-shaped blocks fitting one within the other hinged to each leg andhinged together, adapted to be successively turned into alinement withthe leg and provide an together and hinged to the upper end of theextension therefor in varying the elevation leg, each block havingprojecting portions at of the seat. its opposite ends fitting intocounterpart por- 4.
